Vacuum interrupter |
摘要 |
The present disclosure relates to a vacuum interrupter capable of easily installing a central arc shielding plate in alignment without biasing in a radial direction. The vacuum interrupter includes a protruding guide unit protruding from a stationary electrode seal cup in a perpendicular direction to guide the installation of the central arc shielding plate such that the central arc shielding plate can be aligned in a radial direction. |

1. A vacuum interrupter comprising:
a stationary electrode; a stationary contact coupled to the stationary electrode; a movable contact movable to a position of contacting the stationary contact or a position of being separated from the stationary contact; a movable electrode coupled to the movable contact to support the movable contact, the movable electrode movable together with the movable contact; a ceramic container receiving the stationary contact and the movable contact therein, the ceramic container having upper and lower portions open; a stationary electrode cover plate installed at a side of the stationary electrode and having a central through hole for allowing the stationary electrode to be inserted therethrough; a stationary electrode seal cup connected to seal a gap between the ceramic container and the stationary electrode cover plate, and including a first portion and a second portion perpendicular to the first portion, wherein a plane of the second portion is parallel to a plane of the stationary electrode cover plate; a movable electrode cover plate installed at a side of the movable electrode, and having a central through hole having a diameter greater than an outer diameter of the movable electrode to allow the movable electrode to be movable therethrough in an axial direction; a movable electrode seal cup connected to seal a gap between the ceramic container and the movable electrode cover plate; a bellows having a first end connected to the movable electrode cover plate and a second end connected to the movable electrode to seal a gap between the movable electrode cover plate and the movable electrode, the bellows being expandable or contractible in response to axial movement of the movable electrode; a central arc shielding plate fixed between the ceramic container and the stationary and movable contacts; and a protruding guide unit protruding from the second portion of the stationary electrode seal cup in a direction perpendicular to the plane of the second portion to guide the central arc shielding plate to be installed in a fixed alignment in a radial direction with respect to a lengthwise axis of the stationary electrode. |
